Effect of length, width, and mode on the mass detection sensitivity of piezoelectric unimorph cantilevers
We have investigated both experimentally and theoretically the resonance frequency change of a piezoelectric unimorph cantilever due to the mass loaded at the tip of the cantilever. The piezoelectric
A general method for the conversion of fly ash into zeolites as ion exchangers for cesium
A general method of converting various coal ashes into zeolites was investigated. Fly ashes from several utility power plants were fused with sodium hydroxide at 550 °C followed by dissolution in
Synthesis of zeolites A and X from fly ashes and their ion-exchange behavior with cobalt ions
A modified fusion process was studied to synthesize zeolites A and X from fly ash. It was found that the addition of aluminum hydroxide to the fused fly ash solution followed by hydrothermal
Cytotoxicity tests of water soluble ZnS and CdS quantum dots.
It is indicated that the cytotoxicity of CdS QDs and the lack of it in ZnSQDs were probably due to the presence and absence of the toxic Cd element, respectively, and makes them favorable for in vivo imaging applications.
Non-heavy-metal ZnS quantum dots with bright blue photoluminescence by a one-step aqueous synthesis
We have examined the aqueous synthesis of non-heavy-metal ZnS quantum dots (QDs) using 3-mercaptopropionic acid (MPA) as the capping molecule at various pH and MPA:Zn:S ratios. Transmission electron
Flow Energy Harvesting Using Piezoelectric Cantilevers With Cylindrical Extension
Turbence excitation was found to be the dominant driving mechanism of the PFEH with additional vortex shedding excitation contribution in the lock-in region.

In vitro intravascular imaging results suggest that PMN-PT free-standing thin film technology is a feasible and efficient way to fabricate very-high-frequency ultrasonic transducers.
Modern Breast Cancer Detection: A Technological Review
The state of the art in screening and detection for breast cancer is described as well as a discussion of new and emerging technologies.
Soft-materials elastic and shear moduli measurement using piezoelectric cantilevers
We have developed a soft-material elastic modulus and shear modulus sensor using piezoelectric cantilevers. A piezoelectric cantilever is consisted of a highly piezoelectric layer, e.g.,
Induced voltage of piezoelectric unimorph cantilevers of different nonpiezoelectric/piezoelectric length ratios
Piezoelectric cantilevers are widely used in sensing and energy harvesting devices. For both applications, a higher induced voltage from a given mechanical excitation is desirable to increase the
